HP Capacity Advisor 7.2 User Guide

Glossary
90th percentile That utilization value in the selected time interval which 10% of the utilization values fall above,
and 90% fall below or are equal to.
activate When referring to a logical server, activate means to make a logical server definition available
to be deployed into the computing environment. An active logical server is one that is currently
operating within the computing environment. An inactive logical server is one that has been
defined but is not currently operating within the computing environment.
activated core A core that has been turned on by the HP Instant Capacity (iCAP) software or during installation.
Cores are activated with the icapmodify command (or the vparmodify command in an
HP-UX virtual partition) while HP-UX is running.
active logical
server
A logical server that has been bound to both an managed node and a Matrix OE workload, and
is bound to specific storage. Active logical servers can be in one of two states: powered on or
powered off.
See also inactive logical server, logical server.
agent A program with a well-defined task that runs in the background and that is used to capture
information or do processing tasks.
agentless data
collection
The collection of inventory and performance data from managed systems without requiring
installation or configuration of agents on the managed systems.
annual projected
growth rate
The rate at which utilization of a resource is projected to change.
association In HP Systems Insight Manager, an association is created by discovery and identification
of system objects that are then associated with other objects. One type of association is
1.
containment. For example, clusters contain members, complexes contain nPartitions, and
OS images contain resource partitions.
2. In Global Workload Manager (gWLM), a policy-workload association tells gWLM which
policy to use to manage that workload's resource allocation.
available resources Cells and I/O chassis that are not assigned to an nPartition; or cores, memory, and I/O resources
that are not assigned to a virtual partition. These resources are available to be used in new
partitions or can be added to existing partitions.
average The sum of all the utilization values divided by the number of data points for the selected time
interval.
baseline A timeless demand profile used to generate demand profiles in forecasting.
business period A meaningful time interval (a day or a week) for which to create an Capacity Advisor report.
Capacity Advisor Capacity Advisor. The HP Matrix Operating Environment application that performs analysis and
planning of workloads on a system or across a set of systems.
capacity planning The analysis of and planning for resource usage by workloads on a system or across a set of
systems.
capacity-planning
simulation
The process of combining workload demand profiles, as prescribed by a scenario, to estimate
the demand profiles of the systems that contain the workloads. Statistics gathered from the
simulation can be summarized in reports.
central
management
server
See CMS.
CLI Command line interface. An operating system shell for direct entry of commands by the user.
See also GUI.
cluster A set of two or more systems configured together to host workloads, such that users are unaware
that more than one system is hosting the workload.
CMS Central management server. A system in the management domain that executes the Matrix
Operating Environment software. All central operations within Matrix OE are initiated from this
system.
